Wanted to share that I do have a replacement motor available for the USA Hudson for $175.00.
This motor addresses issues with the original:
Operates at a higher top speed when run at max track voltage.This addresses the complaint by some that it's top speed was too low.Has ball bearings on both ends of the motor for lifetime reliability.Video of a USA Trains Hudson motor with a failed bearing on the worm gear end: (With the upgrade motor you will never have this)

Given that USA Trains has been out of stock on these motors for a couple of years this helps provide an option.
